Answer:
The correct answer is: adaptive immunity.
Explanation:
Adaptive immunity (also called acquired immunity) is one of the two parts of the immune system.
Unlike the innate immunity that responds to any pathogens, the adaptive immunity is highly specific and provides long-lasting protection because once the cells from adaptive immunity contact the antigen (any molecule that triggers an immune response) they become ready to fight them again later in life with a much more efficient approach - this is what is known as immunological memory and is the reason vaccines work.
Acquired immunity does not need a stimulus to exist, unlike innate immunity (the later only acts when there are pathogens involved).
The acquired immune system is mostly integrated by lymphocytes.

Explanation:
While Glycolysis and the Citric Acid Cycle make the necessary precursors, the electron transport chain is where a majority of the ATP is created. The Electron Transport Chain makes energy ... At the end of the chain the electrons are taken up by oxygen molecules to make water. This is why oxygen is known as the final electron acceptor.
Ionic and Covalent bonds
Ionic bonds : Is a chemical bond between a metal and a non-metal and an electron Transfer takes place.
Covalent bonds: A chemical bond between two non-metals and an electron
Sharing takes place.
